# Slack Backup Skill

Backup directory: `~/.openclaw/doc/backup/`

**Strict rules (must be followed — violations are treated as critical errors):**
- **Do not** use write/edit tools to create or modify any files
- **Do not** create Python scripts, test scripts, or any auxiliary files
- **Do not** generate, guess, or fabricate file contents and write them to disk — even if the filename is known
- **Only** run `slack_backup.sh` via exec to download real files
- **Must** verify that the script outputs `SUCCESS: /path/to/file` and that the file exists with size > 0
- If the script reports `ERROR`, inform the user honestly — do not fabricate a success status

## Smart Matching: Interpret Intent → Set Variables → Call Script

The agent interprets the user's natural language, determines intent, sets the corresponding environment variables, then calls the script.

| User says | Environment variables |
|-----------|----------------------|
| "Back up the latest file" / "Back up this file" | (default, no variables needed) |
| "Back up the last two files" / "Back up these two files" | `LIMIT=2` |
| "Back up files starting with report" | `NAME_PREFIX=report` |
| "Back up files with contract in the name" | `NAME_CONTAINS=contract` |
| "Back up the PDF I just uploaded" / "Back up the PDF from just now" | `MINUTES=5 FILE_TYPE=pdf` |
| "Back up the video I just uploaded" | `MINUTES=5 FILE_TYPE=video` |
| "Back up the image I just uploaded" | `MINUTES=5 FILE_TYPE=image` |
| "Back up the last three files" | `LIMIT=3 MINUTES=10` |
| "Back up all PDFs from the last 5 minutes" | `MINUTES=5 FILE_TYPE=pdf LIMIT=5` |

**FILE_TYPE values**: `pdf` / `image` / `video` / `doc` / `file` (default — matches all)
